A recent study concluded that a giant cloud of ash and gases released by the volcano Vesuvius in 79 AD took about 15 minutes to wipe out all of the inhabitants of the city of Bombay, according to what was published by a newspaper report The Guardian Britain, Monday 22 March 2021.
The study confirms that there was no escape for the population, and that most of those died They suffocated in their homes and their bedsOr in the city streets and squares. Essaya’s model estimates that ash, gases, and volcanic particles completely enveloped the city in 10 to 20 minutes.
2,000 people suffocated to death at Vesuvius
The lava of Vesuvius did not flood the 2,000 victims who could not escape from the ancient Roman city, but were suffocated by gases and ash, then covered in volcanic deposits that preserved their physical bodies for a century after.
The study, conducted by researchers from the Department of Earth and Geological Sciences at the University of Barry, in cooperation with the National Institute of Geophysics and Volcanology (INGV), and with the British Geological Survey in Edinburgh, revealed the duration of the so-called volcanic flow, which is a dense and rapid flow of solid lava chunks, volcanic ash, and gases Hot, which struck the ancient Roman city minutes after the volcano erupted.
The mixture may have “reached a temperature of more than 100 degrees Celsius, consisting of carbon dioxide, chlorides, particles of burning ash and volcanic gases,” said Roberto Issaya, a senior researcher at INGV’s Vesuvius Observatory.
He added, “The main objective of the study was to develop a model to try to understand and measure the effect of volcanic flow on the unknown area of Bombay, 10 kilometers from Vesuvius.”
A blazing cloud of ash wiped out everyone
“It is possible that dozens of people died from the volcanic rain that fell on Bombay after the explosion, but most of the population suffocated to death,” Isaya said, adding that the volcanic flow reached Bombay minutes after the explosion.
He also added that those 15 minutes inside that infernal cloud must have seemed endless. The residents could not have imagined what was happening. The people of Bombay lived with earthquakes, but not with volcanic eruptions, so they were taken by surprise and wiped out by a burning cloud of ash.
INGV research describes the volcanic flow as the “most devastating effect” of an explosive eruption. And as “similar to avalanches, they are generated by the collapse of a volcanic column. The resulting volcanic ash extends along the slopes of the volcano at a speed of hundreds of kilometers per hour, at high temperatures and with a high concentration of particles.”
The most attractive Italian attractions for tourists
Today, the ruins of Bombay are the second most attractive Italian attractions for tourists, after the Coliseum in Rome. Last year, they were visited by about a million tourists.
“It is extremely important to be able to reconstruct what happened during the last eruption of Vesuvius, starting with the geological record, with the aim of tracking the characteristics of volcanic flow currents and their effect on the population,” said Professor Pierre Francisco Delino of the University of Barry.
“The scientific approach adopted in this study reveals the information in the lava deposits that clarifies new aspects of the Bombay eruption and provides valuable insights into explaining the behavior of Vesuvius, as well as in relation to civil protection,” Delino continued.
